Just wanted to share to give others the idea. This first pic is about 5 seconds after hitting it with my Fenix P1: The second is 5 minutes later. Now to be fair it is a bit brighter to the eye then what is showing up in the picture: Just wanted to give others a visual idea of how it turns out. It is not really all that fantastic, but ok. The dull light goes on for about an hour and then is almost completely gone. It does have a very faint almost not noticeable glow for many hours, but I am not even sure it would be enough to sight with in pitch black, let alone low light. Still, my sights are definitely more visible in regular daylight even. Oh yeah and this is the super duper Glow V10 one for the record. I will post what it looks like in full light in a minute here.
